A lightweight bout between Edson Berto (14-5-1) and Mike Aina (9-6-1), as well as Crafton Wallace (15-3-1) and Lorenzo Borgomeo (4-0), have all been targeted for the preliminary card of EliteXC’s Oct. 4 event.

EliteXC Vice President Jared Shaw confirmed the list of probables with MMAjunkie.com (www.mmajunkie.com) on Monday.

The upcoming card, which is the third installment of the “Saturday Night Fights” series on CBS, takes place at the BankAtlantic Center near Fort Lauderdale, Fla.

A fight between Cristiane “Cyborg” Santos and Yoko Takahashi has been slated for the preliminary card but could appear on CBS if time permits.

The event’s other top preliminary fight features Berto, a Florida-based fighter who’s 2-2 with EliteXC, pitted against Aina, who recently defeated Kaleo Kwan at EliteXC’s June show in Hawaii. (However, Aina may be best known for a close, split-decision loss to Nick Diaz at a September 2007 EliteXC event.)

Shaw said the organization is simply waiting for Berto and Aina, who have agreed to the bout, to sign contracts.

Wallace, a UFC and Strikeforce veteran, has also been tapped for the preliminary card. Despite losses to Nate Marquardt and Martin Kampmann in his two UFC fights, Wallace has won his past four fights and six of his past seven. He’s garnered a solid reputation fighting throughout Florida, which included a 3-0-1 mark with the Florida-based Absolute Fighting Championships.

Shaw also said the organization plans to book Borgomeo, who will return to EliteXC for the first time since his second-round submission victory over Mike Bernhard at EliteXC’s February show in Miami. Since then the welterweight fighter picked up a first-round TKO over Clifton Weston for his fourth consecutive stoppage victory.

With the card taking shape, Shaw is confident that the Oct. 4 event and the headline bout between Kimbo and Shamrock will be a hit — even though ratings for the second CBS show dropped dramatically back in June compared to its May debut on the network.

“We knew the ratings were going to be significant lower (for the second show),” Shaw said. “We were on a shorter timeframe with a five-week promotion. We were missing some of the major faces that we’ve been building as the foundation of our company, and as well, you’re sitting in the worst time of the year, which is the summer at the end of July when everybody is traveling. Everyone is on vacation.

“In October everybody’s home. Baseball’s been on. There are great lead-ins. College football’s been on CBS. New, brand new hit shows — new reality shows, new sitcomes, dramas — are great lead-ins. (There are) great times for everybody’s eyeballs to be on television to see the possible commercials and to see the Kimbo Slice act.”
